iAnalyzer

Necessary to add the curve K weighting. Necessary to add signal reading option between "Peak", "RMS(300ms)", "RMS(400ms)", and "RMS(600ms)".

After having paid for the app with full features in the pre “pro version” past I have lost features due to an “update” download. I'm presently being extorted to pay for features I had paid for and have been deceived into losing. Other than that…

After yrs of use, the audio has been disabled. How come ?

To the developer, since the subscription, There is this strange notch filtering that won’t go away. The app is great when it’s working but this notch filtering renders it useless.

The free version works. The full version does not work at all. The tech support seems to lead me to a wrong site.

The app is good in its graphic display but lacks an important feature - the ability to rename files. Which are automatically named by the app as you save. The names assigned are just numbers representing the date.

IAnalyzer is an outstanding audio spectrum analyzer app with several unique features. IAnalyzer not only shows the spectrum of a sound, with the frequency and dB indicated, but it also identifies what musical note the loudest peaks are close to, and how many cents sharp or flat these peaks are. This is extremely useful for tuning / manufacturing complex musical instruments where the harmonics of the note need to be tuned along with the fundamental. IAnalyzer is also unique in its ability to record a sound and freeze the action during playback so that the details of the sound spectrum and it's harmonics can be examined. You drag the recorded sound track forward and backward on the bottom of the screen with your finger while examining the detailed audio spectrum of the sound on the top half of the screen. This feature is extremely helpful when trying to examine very transient sounds like the sound of a Mallet hitting a marimba key, or "tap tuning" a marimba resonator. It allows you to examine the attack and decay of the sound as a whole, as well as the behavior of the individual harmonics. Most music instrument apps fail to lock in on very brief percussion sounds, and I have not found another audio spectrum app that combines the ability to freeze the action of percussion sounds while also identifying the musical notes for the peaks that appearing the sound spectrum, I have many different musical instrument tuner apps, but iAnalyzer has become my "go to " app for tuning mallet instruments and their resonators.

Now it doesn't seem to work on iPhone4s and that's no good, I retract my previous 5 stars and will not give them back until this is fixed

There is about 50 db of noise in a dead silent room. Should be a way to fix this. A paid app should be accurate. Current scaling is way off.

Very practical app and elegant graphics. I would like to see the dB vertical scale as we can see the horizontal Hz scale. I hope it will also work with the USB line/mic in and more important, be able to insert recorded wav files so that one can check his recordings. Without those possibilities, it is too expensive for what it does right now. Please update !
